The HW question gives K3P compound and asks for Lewis Structure to be written? Would anyone know why the final answer is spaced out in such a way? Also, would anyone know why only P has brackets around it, but not K? Thank you in advance!

This is an ionic bond therefore there are no electrons shared. That is why it is spaced out with no lines that indicate covalent bonds. Phosphorus P has brackets (at the center) with the charge 3- since it gains 3 electrons from each Potassium K. This is signified by the + sign by each K ion which transfers its electrons to complete a full octet for Phosphorus.
